how do I call run() from command line? this is ts file

run-signing-client.ts

import { SigningClient } from './signing-client';

const awsVars = {
  awsAccessKey: process.env.AWS_KEY_ID,
  awsSecretAccessKey: process.env.AWS_SECRET_ACCESS_KEY,
  s3BucketName: process.env.S3_BUCKET_NAME,
  awsRegion: process.env.AWS_REGION,
  assetsHost: process.env.ASSETS_HOST,
  zappToken: process.env.ZAPP_TOKEN,
  zappPath: 'zapp'
};

export function run() {
  console.log('creating signing client with vars', awsVars);
  const client = new SigningClient(awsVars);

  console.log('checking for pending builds');
  client.processPendingS3Builds();

}
